"afraid to miss" or "afraid of missing"

Question

Afraid as an adjective means ‘feeling fear’. We use it with of + noun, of + -ing form, a to-infinitive or a that-clause Cambridge Dictionary

We can use of +ing or to-infinitive with afraid, how to know what we should use?

Which one of the following is correct? what is the difference in meaning between them?

• I hurried to the station. I was afraid to miss my train.

• I hurried to the station. I was afraid of missing my train.

Answer 1

Whereas afraid to do something describes the feeling of fear (or uncertainty) about something you are on the point of doing:

She was afraid to say what she really meant,

afraid of doing something talks in much more general terms of this fear that applies to any time or situation:

Some old people are afraid of walking alone at night in the dark.

So, in the situation of feeling fear about possibility of missing a train, it would be

I hurried to the station. I was afraid to miss my train.
